Beating the optimal verification of entangled states via collective strategies
This work presents a collective strategy for verifying entangled quantum states that can reach efficiencies beyond those obtainable with the standard global-measurement approach, while preserving unused copies. The protocol is scalable across various platforms and is able to provide information about noise in the system.
